<p>The Scribe framework provides a set of classes for reading and manipulating structured rich text documents. Unlike previous rich text support in Qt, the new classes are centered around the <a href="qtextdocument.html">QTextDocument</a> class rather than raw textual information. This enables the developer to create and modify structured rich text documents without having to prepare content in an intermediate markup format.</p>
<p>The information within a document can be accessed via two complementary interfaces: A cursor-based interface is used for editing, and a read-only hierarchical interface provides a high level overview of the document structure. The main advantage of the cursor-based interface is that the text can be edited using operations that mimic a user's interaction with an editor, without losing the underlying structure of the document. The read-only hierarchical interface is most useful when performing operations such as searching and document export.</p>
<p>This document is divided up into chapters for convenient reference:</p>
<ul>
<li><a href="richtext-structure.html">Rich Text Document Structure</a> outlines the different kinds of elements in a <a href="qtextdocument.html">QTextDocument</a>, and describes how they are arranged in a document structure.</li>
<li><a href="richtext-cursor.html">The QTextCursor Interface</a> explains how rich text documents can be edited using the cursor-based interface.</li>
<li><a href="richtext-common-tasks.html">Common Rich Text Editing Tasks</a> examines some common tasks that involve reading or manipulating rich text documents.</li>
<li><a href="richtext-advanced-processing.html">Advanced Rich Text Processing</a> examines advanced rich text editing tasks.</li>
<li><a href="richtext-html-subset.html">Supported HTML Subset</a> lists the HTML tags supported by <a href="qtextdocument.html">QTextDocument</a>.</li>
</ul>
